LEATHER-BLACKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,606, dated July 2l, 1885.

Application led October 23, 1884.

To all whom, t may concern.-

Beit known that I, J ABEZ HoDsKrNsoN, of Salem, in the county of Essex and State of Massachusetts, have invented certain Improve- 5 ments in Machines for Blacking Leather, of

which the following is a specication.

This invention has for its object to provide a machine adapted to rapidly and thoroughly apply blacking, paste, or other fluid or semifluid material to the surface of sheets of leather spread on a supporting-bed.

The invention consists, as a whole, in an organized machine composed of a bed or support for the leather, two slides or frames, each 15 movable in two directions over said bed, each provided with a series of brushes adapted to bear simultaneously on the leather supported by the bed, each brush having a reservoir communicating with it for thematerial to be applied to the leather, and mechanism for reciprocating the two frames or slides longitudinally, and thereby causing the brushes to distribute the fluid over the surface of the leather, and mechanismwhereby the frame may be moved laterally as the operator may desire to present the brushes to the different parts of the leather.

The invention also consists in certain details of construction, all of which'I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a plan view of my machine. Fig. 2 represents a front elevation. Fig. 3 represents a-n end elevation. Fig. 4 represents an enlarged section on line x x, Fig. l.V Fig. 5 represents a viewl of a modification.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a bed or table supported by a suitable frame-work, b, and serving to support a sheet or sheets of leather to be coated with blacking or other material.

c represents a carriage located over the bed and extending the entire length thereof. Said carriage is adapted to travel on fixed cogged tracks d d, extending across the ends of the supporting-frame b, a shaft, e, provided at ends with pinionsff, meshing with the tracks d, being journaled in ears or bearings g g on the carriage. The shaft e is provided with a handwheel, h, whereby the operator is enabled to (No model.)

rotate it and thus move the carriage laterally over the bed by the engagement of the pinions f f lwith the cogged tracks d d.

t' i represent slides supported by the carriage c, and adapted to reciprocate lengthwise the carriage. Said slides are reciprocated by means of a crank-shaft, jj, journaled in standards la 7c at the ends of `the carriage and connected by connecting-rods j j with the slides iz', each shaft having two cranks, which project in opposite directions, so that the rotation of said crank-shaft will cause the slides to reciprocate simultaneously, but in opposite directions. Each slide supports a series of brushes, Z, which are located below the slides, so that they can act onthe leather on the bed a. Each brush has a tubular shank, m, which communicates with a reservoir, n, in which is placed a quantity of the blacking or other fluid to be supplied to the leather. There is, preferably, a separate reservoir for each brush, the reservoirs being supported by the slides. Each reservoir has a follower, o, which is pressed downwardly on the material by its weight, assisted by springs p lo, if preferred. (See Fig. 2.) A sliding gate or valve, q, Fig. 4, shuts off the blacking or other material when the operator desires. The tubular shank of every alternate brush is adapted to rotate with the brush, and is provided with a pinion, r, (see Fig. 4,) which meshes with a rack, s, affixed to the carriage. (See Figs. l and 4.) rIhe reciprocating movements of the slides cause the brushes that have the pinions r to rotate byv with cog-wheels o', which mesh with the pinions u and receive motion therefrom.

The operation is as follows: The leather be-y p ing in place on the bed, the operator brings the brushes to bear on the upper surface of IOO the leather, and then by means of the valve q allows a suitable quantity of blacking to iiow from the reservoirs to the leather under the bruslies. The driving-shafts t being then set in motion, the slides are caused to reciprocate and thus cause the brushes to distribute the blacking over the surface ofthe leather, the rotation of the journaled brushes facilitating the distribution and making it more uniform. When the leather underthe carriage has been sufficiently blackened, the operator moves the carriage laterally, as above described, and thus presents the brushes to a different part of the leather, and thus the operation is continued until the entire surface of the leather has been acted on. At the end ofthe operation the operator raises the portion of the carriage which supports the slides i i, so as to separate all the brushes from the leather. This portion of the carriage is movable vertically in the parts of the carriage that support the end standards, 7c k. Vertical shafts a a', having at their upper ends bevel-gears b b', are journaled in the standards 7c k, and are threaded at their lower ends, said threaded ends engaging with threaded sockets formed in the vertically-movable portion of the carriage. A horizontal shaft, c c', journaled in the standards 7c k, has at its ends bevel-gears d d,meshing with the bevel-gears b b. When the shaft c is rotated, (by means of a hand-wheel, j, affixed to it,) the shafts a a are simultaneously rotated by the engagement of the bevel-gears, and are thus caused to either raise or lower the vertically-movable portion of the carriage. The operator is thus enabled to elevate and depress all the brushes simultaneously.

Each brush is capable of independent vertical movement, and is pressed downwardly by a spring, g. (See Fig. 4C.) The brushes are thus enabled to yield to inequalities in the surface of the leather, and to be raised and separated from the leather independently, if desired.

A lever, h', Fig. 2, is preferably provided for each brush, said levers being engaged with the shanks of the brushes, the levers being pivoted to lugs on the slides When the outer end of a lever h is depressed, the brushshank engaged therewith is raised, as will be readily seen.

I do not limit'myself to the described details of construction, but may modify the same variously without departing from the spirit of my invention.

In Fig. 5 I have shown a modification of the mechanism for reciprocating the slides i and rotating the brushes. In this modification a driving-shaft, t, imparts motion through bevel-gears to a vertical shaft, j, this being gearedto another shaft, 7c', having at its lower end a crank, Z, which is connected by a rod,

mi', with one of the slides i, and reciprocates the slide. The shaft k has an eccentric pulley,

az, which is belted to an eccentric pulley, q',

on the shank or arbor of one of the brushes Z. The eccentricity ofthe pulley n is such that self, however, to either mode of operation,V

but may either oscillate the brushes or rotate them continuously. If desired, all the brushes may be rotated instead of every alternate brush, or all the brushes may be non-rotating.V

Instead of providing a series of independent reservoirs n, a single reservoir may be employed communicating with all the brushes. The reservoir or reservoirs may be on a support which is independent of the slides, the connection with the brushes being effected by flexible tubes.

rlhe carriage may have one or any other desired number of slides instead of two.

l. In a machine for applying blacking or other material, the combination of a supporting-bed having lateral guides, a carriage located over said bed and capable of lateral movement on said guides, a slide or slides supported by the carriage and capable of longitudinal movement thereon, a series of brushes supported by each slide, and mechanism, substantially as described, for reciprocating the slide or slides, as set forth.

2.
